You should repair your flat roof the moment you notice a problem because this will prevent the exacerbation of the problem, which could lead to a much more expensive flat roof replacement. You will also avoid problems caused by a leaky roof, such as damage to walls and ceilings, mold growth, which can lead to upper respiratory tract problems, increased energy bills, and damage to clothes and other household items due to dampness. Below tips will help you during flat roof repair.
Check if workmanship warranty still applies
Do proper flat roof leak location
- Measure the distance from where you are seeing the leak (on the inside) to the two nearest walls.
- Go to the rooftop and use these measurements to determine, albeit roughly, where the search should begin.
- Sweep the roof to remove any dirt or debris that may make the leak invisible.
- When trying to pinpoint the point of entry, determine the direction of the slope (most flat roofs are slightly sloped to allow for runoff) and check up the slope since you expect water to be running downhill.
- Be on the lookout for popping screws, punctures, worn spots, rips, blisters, seam separations, and other imperfections in the roof’s membrane.
- If you do not find damage to the membrane, look at nearby caulk around vents and other structures, vent pipe boots, and flashing for damage.
Call us in if you are unable to locate the source of the leak, which is quite common. We have been around for 18 years and our roofers have the skills, training, and experience necessary to do this.
Care should be taken when doing this inspection because of the height. At BRENO Roofing, we have ladders that are rated for different weights, meaning our roofers can work safely. In case of any mishap, we carry workman’s compensation insurance to indemnify you.
Check if manufacturer warranty still applies
If you require repairs due to the disintegration or malfunctioning of the roofing material, check the manufacture warranty since you may still be covered. These warranties usually cover you for 5 to 20 years, depending on the roofing material.
At BRENO Roofing, we are manufacturer-certified roofers for some of the top roofing manufacturers in Canada. This is important because if you were to attempt doing repairs yourself, you risk voiding the warranty.
At BRENO Roofing, we offer a 15-year warranty on the workmanship
Use material-specific repair methods
- If you have small punctures or holes in your EPDM flat roof, apply rubber sealant on the area and tool with a knife. For a BUR roof, apply tar to the area using a caulk gun and smoothen it using a brush or a putty knife. For a PVC or TPO roof, you will need a heat air gun to mend the area.
- For membrane blisters, use a utility knife to cut through the bubble, end to end. Dry the area under the blister using a small propane torch or a towel. Apply appropriate roof repair material such as tar, peel, roof cement, and stick patch. At BRENO Roofing, we use 6d roofing nails to secure the blister flaps in place and then cover the head of the nails with roof sealant, tar, or peel, depending on the roofing material, and then stick flashing patch.
- In case of large tears and rips, the same type of repair as with membrane blisters is done, but of course at a larger scale. Rolls of membrane are available for sale with different dimensions.
